The information will now be compared with Malaysian military radar data to help narrow the search area.

Authorities have also revealed data had been deleted from a flight simulator recovered from the home of the pilot of the missing Malaysia Airliner.

Transport and defence minister Hishammuddin Hussein told the news conference this morning that investigators are trying to retrieve the files.

He also said that the pilot, Captain Zaharie Ahmad Shah, is innocent until proven guilty of any wrongdoing.

There have also been reports of a low flying jumbo jet being sighted above Kuda Huvadhoo in the Maldives.

Police are considering the possibility of hijacking, sabotage, terrorism or issues related to the mental health of the pilots or anyone else on board, and have asked for background checks from foreign agencies on all foreign passengers.
